I had BBL 3 and 1/2 weeks ago. Fat was taken most from above knees and inner knees and thighs. Surgeon saus my fat was stubborn at hard to get out. I am still VERY swollen and VERY stiff. Not able to bend my knees more than 30 degrees. Need help to get dressed/undressed. When will it go away? Is it normal? Also, I had a lipo at the same areas 1 year ago. Please help!
